BF2S Forums Physics question regarding "G's"

Ok I am just a nerd and have been thinking of something but I can't figure out the answer. It has to do with accelerations. So picture this:

You are strapped (voluntarily haha) to a rocket moving east doing a constant 4 G's. What would happen if you rotate your seat to face backwards instead of forwards in say 1 second? Would this be the equivalent of going from 8 to 0 g's in 1 second? I can't exactly picture what would happen. Part of me thinks it would mean nothing because your body everything is still accelerating in the east direction. But then again, your internal organs would be pressing in a different direction this time.

Please let me know what you think, I'm kinda curious to see if this could potentially be hazardous to the body.

The rocket has a constant acceleration of 4 Gs.

Why don't we just say that the guy is not on a rocket, but strapped into a centrifuge machine they use for Space training and research.

They can easily provide constant G-Force.




Some interesting stuff I found at Wiki about G-force.

Strongest g-forces survived by humans
Voluntarily: Colonel John Stapp in 1954 sustained 46.2 g in a rocket sled, while conducting research on the effects of human deceleration. See Martin Voshell (2004), 'High Acceleration and the Human Body'.

Involuntarily: Formula One race car driver David Purley survived an estimated 179.8 g in 1977 when he decelerated from 172 km·h−1 (107 mph) to 0 in a distance of 66 cm (26 inches) after his throttle got stuck wide open and he hit a wall.[1]
